100G QSFP28 BIDI 80km

The Q28-100G-BD-LU80/LD80 is a 100Gbps BIDI QSFP28 ZR4 lite transceiver, designed for extended-range applications with up to 80 km of 100GBase-BX throughput over single-mode fiber (SMF) using LC connectors. Its robust design enables reliable high-speed connectivity for data centers, storage area networks, and 100G Ethernet. This transceiver operates bidirectionally, supporting two wavelength configurations. The Q28-100G-BD-LD80 transmits at 1295.56, 1300.05, 1304.58, and 1309.14nm, while the Q28-100G-BD-LU80 transmits at 1273.54, 1277.89, 1282.26, and 1286.66nm, both with complementary reception wavelengths. For optimal use, it requires pairing with compatible devices of matching wavelengths. With digital diagnostics through its QSFP28 MSA-compliant I2C interface, the Q28-100G-BD-LU80/LD80 supports real-time monitoring of key parameters. Easy to install and hot-swappable, this transceiver is ideal for scalable, high-demand network environments, offering flexibility and reliability for long-distance data transmission.

Note

1.       Power on is defined as the instant when supply voltages reach and remain at or above the minimum specified value.

2.       Fully functional is defined as IntL asserted due to data not ready bit, bit 0 byte 2 de-asserted.

3.       Measured from falling clock edge after stop bit of read transaction.

4.       Measured from falling clock edge after stop bit of write transaction.
